Answer:
y= 1x - 1
Step-by-step explanation:
Slope-intercept form: y=mx + b
(-4,-5) (5,4)
m= (y2 - y1)/(x2 - x1) = (4+5)/(5+4)=1
4=1(5)+b
4=5 + b 4-5=b b= -1
y= 1x - 1
Answer:
I think your forgot to add some parts of this question, because you can't do anything with this except simplify it down a little maybe. But, I will provide the simplified version of this.
![\frac{x-4}{x^2-2x}+\frac{4}{x^2-4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-4%7D%7Bx%5E2-2x%7D%2B%5Cfrac%7B4%7D%7Bx%5E2-4%7D)

Answer:
C
Step-by-step explanation:
because you have to foil then do -b/2a
Answer:
Sally has 1,532 stickers remaining.
Step-by-step explanation:
First, you have to determine the total amount of stickers Sally bought by multiplying the number of sheets she bought for the number of stickers in each sheet:
124*14=1,736
Now, you have to subtract the number of stickers Sally gave away to her family and friends from the total amount of stickers she bought:
1,736-204=1,532
According to this, the answer is that Sally has 1,532 stickers remaining.
Equation to find number's value: ![\frac{1}{5}n + 3n = 2n + 42](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7Dn%20%2B%203n%20%3D%202n%20%2B%2042)
Number's value: n = 35
Explanation:
Let n be the unknown number for this problem.
One fifth of a number is the same as
.
Three times the number is the same as 3n.
Twice the number plus 42 is the same as 2n + 42.
So, using the information we've gathered so far, we can create the equation that will provide us with n's value.
Equation: ![\frac{1}{5}n + 3n = 2n + 42](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7Dn%20%2B%203n%20%3D%202n%20%2B%2042)
We can use this equation to find n's value.
You can subtract 2n from both sides to get the equation
, which is the same thing as the equation we were using.
Now add n and
together to get
.
After you do this, your equation should look like
.
Now divide both sides by
to get n's value.
n = 35
